suspects

WASHINGTON  — The Supreme Court cast doubt Monday on whether police may obtain cellphone data to find crime suspects.

In a 6-3 decision, the justices said this location data showing where a cellphone user has traveled is personal and private and subject to the protection of the 4th Amendment’s ban on unreasonable searches.

Justice Elena Kagan said these “records serve as a personal journal of a user’s movements.”

She said the data “resembles other private materials—think of emails, documents, photographs, or calendars—that even if stored on Google’s servers, a user reasonably views as his own…and reasonably expects to be shielded from the inquisitive eyes of the government.”

Because an “individual has a legitimate expectation of privacy in his cellphone location data,” she said police investigators need a valid search warrant from a magistrate.

The court stopped short of deciding the proper basis for a search warrant in such cases. Instead, the justices sent the case back to judges in Virginia.

But the outcome casts doubt on “geofence warrants.”

In recent years, police have gone to Google and cellphone companies seeking tracking data on cellphones that were at a crime scene. Some times, they have had a warrant from a magistrate.

Civil libertarians say the use of this tracking data raises the specter of mass surveillance on innocent people.

Police and government lawyers say no one has a reasonable right to privacy when they are walking on a sidewalk or driving down the street.

The case before the court arose from the armed robbery conviction of a Virginia man who stole $195,000 from a credit union in a small town near Richmond.

By the time police arrived, the robber had fled. But surveillance cameras showed he was carrying a gun and a cellphone.

Lacking other leads, detective Joshua Hilton asked a judge to issue a special type of warrant seeking information from Google.
Referred to as a “geofence warrant,” it seeks data from phones in a particular area at a particular time.

The detective sought data on phones that were within 150 yards of the credit union within one hour of the late afternoon robbery.

After examining and paring down the data, the detective asked for the phone records of Okello Chatrie. Then, with a search warrant of his home, investigators found two robbery-style demand notes, a semi-automatic pistol and about $100,000 in cash.

A judge refused to suppress the evidence from an allegedly unconstitutional “search”, and Chatrie entered a conditional guilty plea.
The full 4th Circuit Court of Appeals split evenly on the legality of the geofence warrant, and the Supreme Court agreed to decide the issue in Chatrie vs. U.S.

Usually investigators obtain warrants to search the home or vehicle of a known crime suspect.

The new and disputed geofence warrrants seek to find a suspect by examining data on the cellphones that were at the scene of a crime.

The FBI used this cellphone data in 2021 to identify suspects who broke through police barracks on Jan. 6, 2021, and pushed their way into the Capitol to disrupt the official counting of electoral votes.

Chief Justice John G. Roberts and Justices Sonia Sotomayor, Neil M. Gorsuch, Brett M. Kavanaugh and Ketanji Brown Jackson agreed on the outcome in Chatrie vs. U.S.

In a 21-page dissent, Justice Samuel A. Alito said the court had “carefully set the stage for its planned performance: striking a pose as a great champion of privacy in the digital age. I cannot support this irresponsible escapade.”

Justice Clarence Thomas agreed.

Justice Amy Coney Barrett agreed in a one-paragraph dissent. “Chatrie had no reasonable expectation of privacy in data about his public movements that he voluntarily disclosed to Google,” she said.

WASHINGTON  — A divided Supreme Court heard arguments Monday on whether the police use of phone tracking data violates the Constitution’s protection against “unreasonable searches.”

Most of the justices sounded wary of barring investigators from obtaining precise location history from Google or cellphone providers if it helps find a murderer or a bank robber.

“I’m trying to figure out why this was bad police work,” Justice Brett M. Kavanaugh told an attorney representing the defendant, Odell Chatrie.

He said a police detective in Virginia was seeking clues to find a bank robber and sought a “geofence warrant” from a judge that told Google to turn over data from phones that were near the bank during the hour of the robbery.

“In the end, he got three names,” Kavanaugh said, including Chatrie, who pleaded guilty. He said these searches have proved to be practical for finding criminals.

But other justices said the court should not rule broadly to endorse digital searches of vast data bases held by private companies.

What about emails or Google photos, asked Justices Sonia Sotomayor, Neil M. Gorsuch and Amy Coney Barrett.

All three said this information deserves more privacy protection than location data.

In the past, the court has said the 4th Amendment protects against government searches that intrude upon a “reasonable expectation of privacy.” The two sides in this case differ on whether a digital search of location data violates privacy rights.

Gorsuch said he was generally skeptical of broad searches if the government had no particular suspect.

Is it OK to search “all the rooms in a hotel for a gun or all the storage units or all bank deposit boxes for the pearl necklace that has been stolen?” he asked.

Eric Feigin, a deputy solicitor general, said the government probably could not obtain a search warrant for all storage units or hotel rooms, but a Google search is different because it is a software filter.

Chief Justice John G. Roberts Jr. proposed a narrow ruling.

Perhaps unwittingly, Chatrie had agreed to have Google store his location history data. Roberts said he could have turned off the public location data, and for that reason, he may have lost his right to appeal.

“If you don’t want the government to have your location history, you just flip that off,” he said.

Justice Samuel A. Alito Jr. agreed. Chatrie “voluntarily disclosed to Google the information about where he was going to be,” he said.

Eight years ago, Roberts wrote an opinion for a 5-4 majority that said investigators needed a search warrant before they could obtain 127 days of cell tower records that helped convict a Michigan man of several store robberies.

Four of the court’s liberal justices joined that majority, but only two of them — Sotomayor and Elena Kagan — remain on the court.

Since then, Kavanaugh, Barrett and Justice Ketanji Brown Jackson have joined the court.

The National Assn. of Criminal Defense Lawyers and other civil liberties groups backed Chatrie’s challenge to the government’s use of geofence warrants.

Chatrie had “a reasonable expectation of privacy in his location history given both its sensitive and revealing nature and the fact that it was stored in his password-protected account,” Washington attorney Adam Unikowski told the court. “There was not probable cause to search the virtual private papers of every single person within the geofence merely because of their proximity to the crime.”

Feigin, the Justice Department attorney, said a ruling for Chatrie “would impede the investigation of kidnappings, robberies, shootings and other crimes.”

He agreed, however, that email should be protected because it involves personal communication.

The justices will hand down a ruling in Chatrie vs. U.S. by the end of June.
